In a show with bloody deaths every week, and compulsion and whatever other fresh hell rushing through town, I just don't think this 키스 is a huge betrayal. At this point, I wouldn't find a relationship between Elena and Damon a big betrayal.

The show has done an excellent job of slowly building the trust between these two until that trust and mutual attraction could only logically be dealt with in a kiss, as it finally was in the end of this episode.
